Unless stated otherwise, the properties of fused silica (quartz glass) and germania glass are derived from the SciGlass glass database by forming the arithmetic mean of all the experimental values from different authors (in general more than 10 independent sources for quartz glass and T g of germanium oxide glass). The list is not exhaustive.
A true flat white ought to have the same quantity of extracted coffee as any other beverage on the coffee menu (generally 30 ml, 1.1 imp fl oz) but because it is served in a smaller vessel (175 ml, 6.2 imp fl oz) it has stronger flavour than say a latte which is normally served in a 225 ml (7.9 imp fl oz) vessel and is subsequently milkier.
A cortado is a Spanish beverage consisting of espresso mixed with a roughly equal amount of warm milk to reduce the acidity, [1] [2] although the exact ratios have considerable regional variation. [3] The milk in a cortado is steamed, but not frothy and "texturized" as in many Italian coffee drinks. [4] The cortado is commonly served all over ...
White gold is an alloy of gold and at least one white metal (usually nickel, silver, platinum or palladium). [5] Like yellow gold, the purity of white gold is given in karats. White gold's properties vary depending on the metals used and their proportions. A common white gold formulation consists of 90% wt. gold and 10% wt. nickel. [4] Copper ...
Quartz is present in significant amounts. Biotite and/or hornblende constitute the dark minerals. Because of its coloring, it is often confused with granite, but whereas granite contains more than 20% quartz, quartz monzonite is only 5–20% quartz. Rock with less than five percent quartz is classified as monzonite.
a patchy blue colour distribution on some facets; white facet junctions, irregular white abrasions and surface pits, where the treatment either did not "take" or had been abraded away. The brilliant color of these products is the result of optical interference effects produced by layers of metal.
Smoky quartz with spessartine on top of feldspar matrix, featuring different crystal habits (shapes). In mineralogy, crystal habit is the characteristic external shape of an individual crystal or aggregate of crystals.
Rutilated quartz is a variety of quartz which contains acicular (needle-like) inclusions of rutile. [1] It is used for gemstones. These inclusions mostly look golden, but they also can appear silver, copper red or black.
